Product details

Description

Voo Positive Power Supply TONE DISABLE This input has an internal pull-up resistor to Voo.When connected to Vss no tones are generated by any key depression allowing the keyboard to be used for purposes other than DTMF signalling.COLUMN 1-4 These CMOS inputs are held at Voo by an internal pull-up resistor and are activated by the application of Vss.Vss Negative Power Supply (OV) OSC IN, OSC OUT On-chip inverter completes the oscillator when a 3,58 MHz Crystal is connected to these pi
